` means lfforefl'ecting theturning of the log during thesawingoperation'. i i One of the important objects ofthe presentinvention isVto provide 4a 'log turner that includes averticallyinovable bar havinga series of vertically lspaced log engaging teeth carried Vthereby whichteeth effectthe turning of the log on its carriage, means beingprovidedfor raising and lowering the bar, additionalmeans beingprovidedfor clamping the-"bar in any raised or lowered position againstsliding movement.. A-further Objectis to provide alog turner,` of `theabove mentioned character that will at all times be positive and efcientin its operation, the same being further simple in construction,inexpensive, Vstrong and Adurableand further well adapted to thepurposelforwhich 'it is designed. j

*Other objects and advantages of ythe 'iniventi-on will becomeapparentxfrom the `following description whentaken ini connection withthe accompanying drawings.`

1 `A Vseries of vertically spaced log engaging teeth" 7 project from theinner side of the upper portion of the bar 2, and each toothis formed`with a threaded shank 8 that projects through ther opposite side of theybar aridhas a nut 9 threaded thereon for devtachably securing the toothon the bar.

5 The lower end of the bar 2` is secured within a suitable socket 10that isv arranged vertically in a triangular shaped casting l1. Arrangedonopposite sides of the bar 2 for dispositionbetween the floor 1 and thesub- 1 .floor 12 are the cliannelshaped guides 13 and` 14,respectively.` A pair of opposed ychan- 4nel shaped members 151 and `1areattached to'l'the outer face of eachv of the channeled guides toprovide areinforcing structure therefor. The guide `13 and itsreinforcing structure are arranged in a vstationary manner betweentheliioor yl` and-1 the sub-floor 12 on one side off the verticallymovablebar 2, whiletlie opposed guide `unit is pivotally supported atits lower end'- as at 17 for` swinging movement toward or away from" theadjacent side of the toothed bar 2. The

rod 18 is operatively connectedat one-end responding parts `throughout`the several to the -upper` end portion of the pivotally `mounted'gnideunit, the other 4end being adapted to be connected to `any suitable Asshown in Figure 2, the upper end* portion of tlie pivoted guide unit isoperable A pair of rectangular shaped blocks-such Jas are shown at, 20are arranged forlongie spective channeledguides 13 and 14;, and as V' ll shown in Fivure 2 (each block is toothcarrying bar 2 that is V0frelatively u 1S C ear .Y a

windlass (not shown),'and any appropriate means may be provided forwinding or unwinding the cable upon its windlass'.

Normally the parts -are arrangedV as shown in Figure 1 and the castingwith the guide blocks 2O are disposed. adjacent the lower ends of thechanneled guides. When the cableY 23 is actuated to effect an upwardpull upon the casting l1, the blocks 20 will move upwardly in therespective channeled guides and the toothed bar 2 will simultaneously beraised causing the vertically'sp'aced teeth 7 to successively engage thelog 6 and effect the turning movement thereof on its carriage. The logmayV be held in any turned position by exerting 'an inward pressure uponthe rod 18 so that :a clamping vaction is setup by the pivoted guidej14against its adjacent block 20 so that further sliding movement of thetoothed bar and the casting carried by the lewe-rend thereof isprevented. However, upon swinging therpivoted guide'uni't 14 outwardly,to `release the clamping action, the 'blocks 20 are then f-ree to movedownwardly in their respective guidechannels and the toothed bar will belowered.

Furthermore, as will be seen ywhen the pivoted guide 14 has been exertedupon so as to effect a cla1nping.action,for maintaining the bar 2 in anyvertical position between the guide units, toprevent further raising orlowering of. the bar 2, the said bar 2 .may be'rocked upon .its pivotalconnection by proper manipulation of the cable 23, to swing either tothe right or leftvas indicated by broken/lines in Figurehrthe brokenlines therein lillustrating the direcn tion of the bar 2 'when rocked onits pivot l teeth with the log, and a ydownward pullV toward the right.However, when the bar 2 is rocked on its pivotal connection toward ytheleft and the teeth engage ithe log 6' for y bar, means or raising andflowering said turning the same', a tight grip of 'theteeth upon the logwill be effected.

Obviously, then., when the bar is rocked towardthe left to .effect atight grip ofits is applied to the cable 23, the log is raised, it beingunderstood of course that the guide 14 has been moved upon vits pivot asuicient distance to permit of the raising or lowering of thebar 2,whereas on lthe other hand, when the lguide 14 has had sufficientpressure exerted thereupon through the medium of the rod 18 for'clamping the bar 2 stationary between said guide and the othercooperative guide member 13, the bar 2 may then be rocked for movementeither toward or away from the log for any purposes.

It will thus be seen from the foregoing description, that I haveprovided a log turner that will at all times be positive and eicient inits operation and due to its simplicity, the saine can be constructedand installedat a very low vcost.

While I have shown the preferred embodiment of my inventionit is to beunderstood that minor changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention or the scope of the appended claims.

Having thus described lthe invention, what I claim as new-and desire tosecure by Letters Patent is :--v

1. A log turner comprising in combination, a vertically movabler bar,vertically spaced log engaging and turning teeth carriedby the bar, apair of vertically arranged guides disposed on 'opposite sides of thebar, one of the guides being pivotally supported at its lower end, guideblocks carried by the lower end of the toot-hed bar for. cooperationwith the respective guides, means for raising and lowering the toothedbar, and means associated with the pivoted guide for setting up aclamping 'action upon the guide blocks go prevent sliding movement ofthe toothed ar. l

2. A log turner comprising in combination, a vertically ymovable bar,vertically spaced log engaging ,and turning teeth carried by theb'ar, apair of vertically arranged guides disposed on opposite sides of thebar,

one of the guides being pivotally supported at its lower end, guideblocks carried by the lower end of thetoothed bar for cooperation withthe respective guides, means for raising v guide.

3. In a lov turner, a vertically movable bar, means vfor clamping saidbar in a raised or lowered position, said last mentioned means including`guide means for said bar during the sliding movement of said bar,fmeans for pivotally mountingsaid movable .bar between said guide means,and means to swing said bar upon its pivot for engagement with the log.

4. A log turner comprising, in combination, a pivotally mounted casting,a vertically disposed bar secured at its lower end on the casting., flogengaging and turning teeth arrangedk on the bar at the upper end of saidbar, channel guides arranged verti cally on opposite sides ofsaid bar,one ofV said channel guides being pivoted at its lower end, guide blockspivotally secured to the opposite sides of said casting, said guideblocks being slidably disposed Within the respective channel guides, anactuating member connected to the upper end of said pivoted channelguide to set up a clamping action against the adjacent guide block toprevent sliding movement of the casting between the said channel guides,and a common operating mechanism for imparting sliding movement to saidcasting, and for rocking said casting.

5. In a log turner, a vertically movable bar, log engaging and turningteeth arranged at vertically spaced intervals on the bar, means forraising and lowering the toothed bar, guide means for the verticallymovable toothed bar, means for clamping the bar in a raised or loweredposition toV prevent sliding movement of the bar, means for pivotallymounting said vertically movable bar between said guide means, and saidclamping means forming a part of said guide means.

In testimony whereof I aix my signature. 3o WILLIAM H. WIN TERS.
